ABSTRACT:
A facility for conditioning compressed natural gas to be dispensed to vehicle fuel tanks is provided that includes a fuel storage system, a chilling apparatus, and a fuel dispensing system. The chilling apparatus includes a refrigeration system and a liquid separator. The refrigeration system cools the compressed natural gas to near freezing temperature and/or a sub freezing temperature to remove water vapor, to remove higher hydrocarbons, and/or to obtain a full fill of the vehicle fuel tanks. The liquid separator is located downstream of the refrigeration system to remove any condensed liquids from the natural gas. A desiccant bed can be provided downstream of the liquid separator to remove any residual liquids remaining in the natural gas.
